The present thesis presents a technical - economic analysis of the income, costs and investment involved in the mining sector, for this was taken as a case study a narrow vein mining median located in the department of Ica (El Sol Naciente Tercero) property of the mining company S.M.R.L. Gotas de Oro. This report analyzes the increase of 100% of the total production of the mine, due to the start of operation of the Rosita vein; but without significantly reducing the contribution of ore tonnage, of the other mineralized bodies in operation (Vein Gino I, Gino II, Icas I and Icas II). It is scheduled for 2017 to gradually increase the monthly production of the mine, with the aim of reaching 4000 tons per month. For the year 2018 and 2019 it is proposed to maintain this production, prioritizing the exploration work due to the presence of 02 additional veins to the aforementioned, in addition to virgin mineralized bodies that could adequately support future growth projects. So the present research work, first, analyzes the price expectations of the metals involved in this thesis; Second, it describes the geological characteristics of the mining site; third, an updated calculation of the resources and reserves with which the deposit is available is presented. Then the geomechanical studies are presented in a concrete way to carry out an adequate design of the Ascending Cutting and Filling method. The aspects of ventilation are summarized, depending on the requirements of the personnel, equipment and types of work; the auxiliary equipment and services necessary to perform the mining operation are also specified. With all this technical information, we proceed to carry out the program of advances and production on the veins in operation, to comply with the tonnage proposed in this thesis. Obtained the production program and laws per month for the years considered, proceeds to make the valuation of it, considering the market price of metals, involved in the investigation; obtaining income from sales of the concentrate. With the income and costs calculated, the economic evaluation of the El Sol Naciente Tercero mine is performed, that is, the Cash Cost is determined, to determine the operating margin of the mine. In addition, an analysis is made of the necessary investments (Capex) to meet the objectives set. Finally, a one-dimensional sensitivity analysis, conclusions and recommendations of the results obtained are presented.
